Have you tried G major music theory? This site has a lot of pieces, grading from absolute beginner to advanced players. Plus they all have fingering written on them, so you don't have to be uncertain which fingers to use and when.

You can download both the written notes (PDF) and as MIDI. Some people play the MIDI files in Synthesia a program which shows notes falling down to a keyboard, very visual.

Then of course you can watch Andrew's videos (if you haven't) they include a lot of basic information.

You can also get some internet courses for about $40, if you're willing to spend some money. But you should do fine with G major music theory songs and Andrew's videos.
